The invention relates to sanitary facilities and can be used to meet human sanitary and hygienic requirements.
It is known a toilet paper, which is used to maintain human hygiene after defecation and/or after urination. More information is available at http://en.wikipedia.org/wiki/Toilet_paper. The disadvantage of this toilet paper is that the density of toilet paper sheet is all the same as in the central part of toilet paper sheet, and outside the central part of toilet paper sheet, while for using toilet paper is not necessarily that the outer part of toilet paper sheet, surrounding the central part of toilet paper sheet, has the same density as the central part of toilet paper sheet. Without any loss of toilet paper quality the outer part of toilet paper sheet might have a lower paper density. Since the density of toilet paper sheet is the same everywhere, the result is a toilet paper user spends more toilet paper than it needs to maintain his sanitary and hygienic requirements.
It is known the toilet paper (see U.S. Pat. No. 3211145, FIG. 3, column 2, lines 64-72), which includes a front layer of toilet paper made from absorbing materials, in which in its central part is made a circular hole, the inner layer of flexible paper, featuring a low friction, access to which (layer) is carried out through specified circular hole in the front layer of toilet paper, and a back external layer of toilet paper made from absorbing materials. The disadvantage of this technical solution is the technological complexity of manufacturing specified toilet paper and wasteful paper consumption for production of specified toilet paper.
It is known the toilet paper (see U.S. Pat. No. 5,492,746, FIG. 1, column 1, lines 55-64), which consists of three layers of paper: two external and one internal, herewith on external sides of toilet paper to each of external layer of paper in the central part of toilet paper by means of glue water-soluble structurally strong paper coating with high absorption capacity, which does not permit hygienic problems, is attached. The disadvantage of this technical solution is the technological complexity of manufacturing specified toilet paper and wasteful paper consumption for production of specified toilet paper and also requirement for additional materials in the form of additional paper coating. The technical decision proposed in the U.S. Pat. No. 5,492,746 can be considered as the prototype of claimed invention.
The task to be solved by the claimed technical decision and the technical result of the claimed invention is to reduce user's consumption of toilet paper.
With a view of correct understanding and interpretation of used in the present specification and claim terms the following terminology was used:
The central sector of toilet paper sheet is a toilet paper sheet sector, which has a round, or square, or rectangular, or triangular, or oval shape, or elongated oval shape, or rectangular shape with rounded edges, or any other geometric shape, inside of which (sector) the geometric center of toilet paper sheet is situated, herewith: a) outer sector of toilet paper sheet surrounds central sector of toilet paper sheet in whole or in part, b) the area of central sector of toilet paper sheet is equal to, or greater than, or less than the area of outer sector of toilet paper sheet, c) central sector of toilet paper sheet has a higher paper density and/or higher elasticity compared with outer sector of toilet paper sheet.
The outer sector of toilet paper sheet is a toilet paper sheet sector, which surrounds central sector of toilet paper sheet in whole or in part, herewith the area of outer sector of toilet paper sheet is equal to, or greater than, or less than the area of central sector of toilet paper sheet.
Specified technical result is achieved as follows:
In toilet paper, which is a sheet of paper, the central sector of toilet paper sheet has a higher paper average density and/or higher average elasticity compared with the outer sector of toilet paper sheet, herewith the outer sector of toilet paper sheet surrounds the central sector of toilet paper sheet in whole or in part.
The central sector of toilet paper sheet can be divided into two parts: central and outer, herewith the central part has a higher paper average density and/or higher average elasticity of paper, herewith the outer part of the central sector completely surrounds the central part of the central sector of toilet paper sheet.
The central sector of toilet paper sheet may have a heterogeneous density and/or elasticity of toilet paper, herewith closer to the center of toilet paper sheet density and/or elasticity of toilet paper becomes higher.
The area of central sector of toilet paper sheet can be less than the area of outer sector of toilet paper sheet.
The area of central sector of toilet paper sheet can be equal to, or greater than the area of the outer sector of toilet paper sheet.
Toilet paper can have a round, or square, or rectangular, or oval shape, or elongated oval shape, or rectangular shape with rounded edges.
The central sector of toilet paper sheet can have a round, or square, or rectangular, or triangular, or oval shape, or elongated oval shape, or rectangular shape with rounded edges.
The area of toilet paper sheet can be more than 200 sq. cms. (square centimeters), or more than 150 sq. cms., or more than 100 sq. cms., or more than 50 sq. cms., or more than 30 sq. cms., or less than 30 sq. cms.
Toilet paper sheet can be single- or double-layer or multilayer. At least two layers of paper in toilet paper may differ in paper density and/or in elasticity and/or in materials that are applied in their manufacture, and/or in their surface texture.
Toilet paper sheet can be one-colored or multicolored.
Sectors of toilet paper sheet and/or parts of sector of toilet paper sheet may have a different color.
Between sectors and/or parts of sector of toilet paper sheet may indicate the border, herewith specified designation can be carried out through at least one line of color different from colors of sectors and/or parts of sectors of toilet paper sheet.
The central sector of toilet paper sheet may be different from the outer sector of toilet paper sheet in tactile (touch) and/or in texture.
The central part of central sector of toilet paper sheet may be different from the outer part of the same sector of toilet paper sheet in tactile (touch) and/or in texture and/or in elasticity.
On one or two sides of toilet paper sheet can be placed at least one image and/or at least one decorative pattern and/or at least one character and/or at least one pattern and/or at least one geometric shape and/or at least one letter and/or at least one number and/or at least one hieroglyphic symbol.
Toilet paper sheet or sector of toilet paper sheet can be impregnated with a fragrance and/or at least one medicinal agent and/or disinfectant.
Sheets of toilet paper can be interconnected to form a band, herewith a toilet paper sheet can be separated from another toilet paper sheet by perforation or punching.
A band, which consists of interconnected sheets of toilet paper, may be rolled, herewith the outer edge of band of toilet paper can be attached to the roll of toilet paper mechanically or by means of glue or thermal way.
Inside the roll of toilet paper may be a hole, which is a bung inserted into the roll.
Inside the roll of toilet paper may be not a hole and a bung.
Edge of the band of toilet paper inside the roll of toilet paper can be attached to the bung mechanically or by means of glue or thermal way.
The claimed invention is technically feasible as in the prior art all the technical means, components and materials, that allow to produce toilet paper in accordance with the claimed invention, are known.
Significant features of the invention, expressed in the section “Description of the invention” as an alternative for any choice permitted by this alternative in conjunction with other features characterizing the invention provide receiving the same technical result, which is to reduce user's consumption of toilet paper.
The claimed invention can be used to meet human sanitary and hygienic requirements as well as to reduce the amount of paper used.
